The aim of this study was to examine the possible effects of the physicochemical parameters of the water at a fish farm where aquaculture activities are carried out (temperature, pH, salinity, total dissolved solids, electrical conductivity, dissolved oxygen, Secchi depth, nitrite-nitrogen, nitrate-nitrogen, phosphate-phosphorus, ammonium-nitrogen, silica, chlorophyll-a, and suspended particle matter) and in the sediments (%burnable organic matter and %organic carbon). The area of study was an open sea network cage farm where European seabass (Dicentrarchus labrax), gilthead seabream (Sparus aurata), and meagre (Argyrosomus regius) species are cultivated with an annual capacity of 7900 tons in the Bay of Çeşme Ildır (Aegean Sea). Samples of surface and bottom water and sediment were taken seasonally from four stations (three cage and one reference station) between December 2013 and October 2014. The study found that the maximum concentrations of ammonium-nitrogen, phosphate-phosphorus, and nitrite-nitrogen were observed in summer, whereas those of nitrate-nitrogen, silica, and chlorophyll-a increased in spring. In comparison with other studies conducted in the region, the amounts of nutrients, except for silica, were found to be considerably lower. Nonetheless, the values of silica and phosphate-phosphorus exceeded the limits for clean seawater. There has been no similar study conducted in recent years due to increased aquaculture capacity in this bay.

海洋鱼类养殖对水和沉积物质量的影响：伊尔德湾（爱琴海）。

这项研究的目的是检验进行水产养殖活动的养鱼场中水的物理化学参数的可能影响（温度，pH，盐度，总溶解固体，电导率，溶解氧，Secchi深度，亚硝酸盐-氮，硝态氮，磷酸盐-磷，铵态氮，二氧化硅，叶绿素a和悬浮颗粒物）和沉积物中（％可燃有机物和％有机碳）。研究区域是一个开放海网式网箱养殖场，欧洲鲈鱼（Dicentrarchus labrax），金头鲷（Sparus aurata）和微薄（Argyrosomus regius））在切什梅伊尔德尔（爱琴海）湾养殖，年产7900吨。在2013年12月至2014年10月期间，从四个站点（三个网箱和一个参考站点）按季节采集了地表和底部水和沉积物的样本。研究发现，氨氮，磷酸盐-磷和亚硝酸盐-氮的最大浓度为在夏季观察到，而硝酸盐氮，二氧化硅和叶绿素a春天增加了。与在该地区进行的其他研究相比，除二氧化硅外，营养物质的含量要低得多。但是，二氧化硅和磷酸盐-磷的值超过了清洁海水的限值。由于该海湾水产养殖能力的增加，近年来没有进行过类似的研究。
